I have a camera bag problem...I just can't find the right bag. I did manage to get rid of 11 backpacks earlier this year - I kept five of them. The last road trip to Dinosaur I packed two bags for the girls (Fuji and Oly), that was a good idea at the time but the back seat of the truck was full. Two Tripods, four camera bags (Erich had two as well), rain coats, 30 degree jackets, hats, gloves, face masks and more hats. So, we drove out to the Boulder Mike's Camera and picked up the 13L Think Tank Unban Backpack. It is a tight fit but I managed to squeeze all in all my gear. It is a heavy bag! Good thing I only plan on using it in the car!
